報告題目:Topological defects of N-component coupled nonlinear Schrodinger equation: application to ultra-cold atom system
報告摘要:In this talk, we will discuss both the static and dynamics of topological defects, such as soliton and vortex, of N-component coupled nonlinear Schrodinger equation, with the application in Bose-Einstein condensate. By using the variational analysis and numerical simulation, we obtain a variety of sotion and vortex, such as ring dark soliton, vortex-antivortex, half-quantum vortex, twisted and double-quantum spin vortex. Finally, the effects of variously controllable parameters on the statical and dynamical properties of such topological defects are also investigated in detail.
